I use 3S 1800 lipos with the 6000KV setup (The long thin ones for the Tex helis I think are what the advertise them for), they work nice. I actually ran 4S and the 4800KV motor in my T45 but the 3S 6000 is essentially the same power. Here is my T45 build thread:http://www.rcgroups.com/forums/showt...&highlight=t45

Not sure on the Hobbyking ESC, it just needs to be able to run a 6 pole motor at least 70,000 rpm so look at the ESC manual and see if they specify rpm limits, and timing needs to be low around 5 degrees. This is why I sell the ESCs I do on my website, they are 100% compatible with my motors in this regard.

I figured this was a relevant post here since this is all Don's set up... This is a vid I took last week of Micromantis's Firfox looking Screamer... This is for sure the fastest 50mm jet that I have ever seen... And it scared the crap out of me a couple times in this vid...LOL I think that with a slightly larger battery that this thing could really be good!!

Good day guys!
I have this kit, as well as a Katana on the way. Since I already have 1000, and 1800mah 4 cell lipo's kicking around for the Rarebear, figured I'd solicit info around those.
For my Screamer I thought of the 4800, or 5400kv combo, I like 100mph ish speed, so long as a couple more mph doesn't double the amp draw.
Lipo's are in fact inexpensive relative to the effort and time put in, so if the 6000kv 3 cell route works as the best go fast compromise, let me know.
Thanks, dozens of planes, new to the wee edf scene though.
You're experience is appreciated.

well i am sure u can make them work but cg will be a issue . on mine i moved the fan back a bit when i modded it for the wemo and still have to push the 1600 back out of the bay a bit, minor foam cut. with this setup no tail weight was needed and i am just slightly forward on cg. don used a bigger battery and ran his w/ a further forward cg yet.

yours may take some tailweight w/ the 2200 but it will make good power

Yes it has been done, I will not warranty 4S use on the 6000KV. On 3S it is ~400 watts so on 4S will be ~750-800 watts and exceeds the watt rating of the motor and rpm rating of the fan unit and not all ESCs will run that fast of rpm on a 6 pole motor. So it is use at your own risk. Also the rotor will need to be glued to the rotor adapter to prevent slippage.
